Pseudolithos cubiformis problems — and how to fix them
Pseudolithos cubiformis (Pseudolithos cubiformis) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Rapid rot from overwatering
The defining risk. Any excess moisture, especially in cool or low-light periods, can collapse the plant within days. Water minimally and only in warm, bright, actively growing conditions.
Cold damage
Temperatures below roughly 12-15°C cause soft, blackened patches and decline. Keep it warm year-round and never let it sit cold and damp.
Sunburn scarring
Sudden intense sun behind glass scorches the body, leaving permanent corky marks. Acclimate gradually and diffuse the harshest midday light.
Graft dependence and weak roots
Own-root plants are notoriously hard to keep; many are grafted onto Ceropegia or similar stock for vigour. Check whether yours is grafted and water accordingly.
